Application March 11,

Claims.

This invention relates to shuttles and more particularly to means for reducing shock thereto and it consists in the constructions, arrangements and combination herein described and claimed.

It is an object of the invention to provide a detachable or renewable shuttle tip of a shockabsorbing type readily applicable to shuttles of various types whether for light or heavy work.

It is also an object of the invention to provide a novel means for incorporating a resilient cush ion and metallic tip upon the shuttle body.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein b Figure 1 is a sectional view of an end of a shuttle constructed in accordance with my invention.

Figure 2 is a similar view of the invention as applied toa jute shuttle.

Figure 3 is a sectional View of a modified form shown in Figure 1.

There is illustrated a shuttle generally indicated by the reference character l0, and this may be of any usua1 construction whether for heavy or light weaving work.

In Figures 1 and 3 the shuttle represented is that employed in weaving light material such as woolens 0r linens, while in Figure 2 a construction is shown as applied to shuttles employed in weaving material such as jute, the only material difference being in the securement of the nose to the shuttle proper.

In Figure l, the shuttle body is provided with a central medial bore II extending longitudinally, for reception of an anchorage pin l2, which may be circumferentially recessed, as at l3, if desired.

The pin I2 is formed integrally with a plate Hi, the peripheral edges of which are coincident with the contour of the shuttle, and comprises a dovetailed portion l5 for a purpose to now be described.

The portion l5 includes a plate It, the outer edges of which are inclined to provide a positive grip within a rubber tip H, the latter being molded or otherwise shaped to conform to the shape of the shuttle. The rubber or other resilient tip IT! has its forward end enclosed by a metallic portion l8, and in order that the tip l8 will be securely held, the tip includes inturned flanges l9 molded or embedded in the resilient material.

In Figure 3 the shuttle includes a pair of bores lI-a for reception of a like number of retainer pins l2- a on plate M--a, the plate having inturned flanges embedded in the resilient ma- Dundee, Scotland 1939, Serial No. 261,320

terial, the inturned flanges being in symmetry with the contour of the nose of the shuttle.

The resilient material is. indicated at l'|-a and the nose at Iii-a, the latter comprising a stem portion 2! which is divided in opposite directions to provide an anchorage 22. The nose lS-a. is indicated in this instance as a solid member.

In Figure 2 dual anchorage pins l2-b are provided integrally formed with a plate l4-b, the latter being formed with means for securement in the resilient cushion Il-b, and in the present instance, the plate l lb will be perforated for anchorage of the resilient material. A nose [8-12 is provided and in the present instance, the nose has an offset portion 23 as is required in heavy work shuttles. The nosel8-b includes inturned flanges Iii-a affording securement in the resilient material l'l--b.

In all forms of the device it should be understood that both ends of a shuttle will be constructed with cushioned noses, thereby eliminating noise as well as reducing shock to the loom, as well as to the shuttles proper.

It will also be seen that the noses may be readily removed from the shuttle body for deplacement of new noses, since the pins l2, I2--a and 12-42 are frictionally retained permitting prying of the nose from the shuttle.

While I have shown and described certain preferred forms of the device, this is by way of illustration only, and I consider as my own all such modifications in structure as fairly fall within the scope of the appended claims.

I claim:

1. A shuttle for weaving looms comprising a shuttle body, said body having a bore in its ends, a nose for the ends of the body comprising a plate, a pin on the plate frictionally engaged in the respective bores, said plate having anchorage means, a resilient member engaged with the anchorage means, and a metallic point anchored to the resilient member.

2. A shuttle for weaving looms comprising a shuttle body, said body having bores in the ends thereof, a nose for the ends of the body comprising a plate, pins on one side of the plate for frictional engagement in the respective bores, the other side of said plate having anchorage means,

a a resilient member engaged with the anchorage means, and a metallic point anchored to the resilient member.

3. A shuttle for weaving looms comprising a shuttle body, said body having a bore in its ends, a nose for the ends of the body comprising a metallic point on the resilient body, said point having a medially disposed stem, said stem being provided with oppositely directed arms for anchorage in the resilient member.

5. A cushioned tip for shuttles of a weaving loom comprising a metallic plate, means on one side of the plate for securement to an end of a shuttle; a nose, and a relatively thick resilient member positioned between and anchored to the nose and the other side of the plate.
